Bring in a pile of newspapers or choose some online news sites. Give each student a section of the paper and ask them to find something, anything, in the paper that relates to the concept or vocabulary term you are learning.
For example, in a middle school math lesson on polygons, students searched the paper for something related to polygons. After a few moments, students shared their findings with the whole class. Examples included: a picture of a cell phone, a basketball court, a corporate logo and a boxed ad.
